F- PHTL. I just emailed them for a refund: DENIED since I was a Kickstarter backer. So while I have no doubt that the company could refund the interest-free loan I've granted them since November '13, they'd rather I jump through hoops to get my cash back or wait "a few weeks" according to the denial email for the watch. I don't even want the watch anymore... I finally decided to try to get my money back now because I need to build a new NAS, which I need much more than a toy / watch... that I might receive at some point. PHTL is super evasive re: dates and such on their forum, and especially following this experience, I definitely don't want to be doing any business with this company.

Just giving anyone interested an account of my experience as a super-annoyed Hotsmartwatch backer.
[Other SmartWatches] simple1i:
Isn't that the case with all watches from kickstarter and indiegogo?
[Other SmartWatches] JarlSX:
delays don't entitle you to a refund, even if there are people that call the HOT Watch obsolete thanks to the 6 months delay, but that's the risk you take when funding tech projects like these

i do hope all the waiting was worth it, but it might not have a 'long' life with Android Wear on it's way

gotten really used to my SW2 by now, wonder if the private calling function will be enough...

Hello,

Following [MENTION=3609932]Nebucatnetzer[/MENTION] idea (http://xdaforums.com/showpost.php?p=47328274&postcount=1283), I decided to create a new thread dedicated to ART talking.

ART is not even finished by Google : all the ART discussion in 4.4 custom ROMs thread for our GNex clutters the threads with the same question every page. It results in messy threads which do not help anyone who wants to see the status, updates, or wants to post bugreports about the KitKat ROMs !

Small reminder out there : KitKat isn't even fully working on our phone, so it is quite early to mess up with ART, just my opinion ;) So I'll hope everyone will talk about ART here as it concerns all the 4.4 ROMs out there.

What is ART ?

ART, Android RunTime, is a new runtime which has been introduced in Android 4.4.

It has been said that it improves the smoothness of the phone, but ATM it's more of a placebo effect (listen to this please, very interesting : Android Central : five minutes about ART podcast)

How to enable ART ?

Important, as Android devs said : Dalvik must remain the default runtime or you risk breaking your Android implementations and third-party applications.

(source : https://source.android.com/devices/tech/dalvik/art.html)

Go to Settings, then Developer Options, then Select runtime and select "Use ART"

BEWARE : Use odexed gapps (from AOSPA) otherwise you'll have nonstop FC and a really hard time reselecting Dalvik !

Here's a download link :AOSPA Odexed 4.4 Gapps

After selecting ART, your phone will rebuild is cache as usual, but don't worry if it takes a long moment, 20-30mins as some people reported.

If there's any other information we should add to this OP, I'll do it :) So, please use this magnificient thread to centralize all the ART talk :good:

Cheers !

Whatsapp doesn't work with ART

*Just informing*
[Samsung Galaxy Nexus] Mandelbrot.Benoit:
Neither does Titanium Backup. I still get FC on Google keyboard, Google one and some init even with odex gapps. Each reboot there's 16 apps that need to be rebuilt each time. Really sucks.
[Samsung Galaxy Nexus] shahrukhraza:
Has anybody noticed some speed improvements?
[Samsung Galaxy Nexus] seriousia:
Is there any manual way to convert ODEX to OAT ?
[Samsung Galaxy Nexus] j3r3myp:
Don't think so. I think the system does it when selecting ART and rebooting. That's why cache rebuilding takes a longer time.

But I'm not sure at all.

ART

I tried switching to ART last night.

I used Grarak's and ODEXED PA GApps.

After switching to ART, the phone prompted a reboot so I plugged my phone preparing fie a logcat.

When the Google logo appeared I started the logcat.

I noticed 1 error from the very beginning. It's looking for something and it didn't seem to find it.

Then on the process of optimizing the apps, there is one persistent warning.

It says it didn't find "ELF Magic".

What is ELF Magic ?
[Samsung Galaxy Nexus] Edward Stanbury:
i was just thinking, with a fully stock odexed rom, all of the system apps and some frameworks are odexed. so when we are currently using art its only affecting the gapps and nothing else so technically we are not fully using art to its best ability and getting the full effect am i right ? i know its experimental but having the gapps only running with the art runtime is very minimal. i dived around root explorer and i noticed that the priv-app files still contained odex files and not oat showing that the compiler only works on system apps, idk im just babbling on sharing some thoughts haha anyways i would love to try it on a full rom scale some time ;) hope ya guys understand what im trying to say here :D
[Samsung Galaxy Nexus] zAlbee:
ELF file is a kind of executable file used by some Unix-like systems, similar to exe on Windows. The header of the file contains a sequence, called the magic number, which the system will check to make sure it's the right format. If not found, that means it's not an ELF. Search "ELF magic number" for more info.

Hey guys, I just found this video about ART vs. Dalvik. Okay, it is on Nexus 7 (2013), but I guess the weaker OMAP4460 can see some benefits once we have a more-or-less stable build.

Gnex / CM11 by Playfulgod in ART mode

Been playing around with a couple of stock Gnex handsets and various combinations of rom/kernal/etc etc and have got ART running on CM11 rom by PlayfulGod [tried all the others as well!] and have not had any issues with graphics, booting, going back to dalvik, that other homebrew rom installers seems to be having.

Have tried all 5 roms / kernals for 4.4, on both handsets [one was gplay suppled] and cannot see any difference with Apps installed running in ART or Dalvik modes.

Not sure it that helps anyone who is not an expert in all things android [that me!] that is messing around, while G get the real 4.4 update out [sure it is coming soon!] with different updates, installs etc.

1 Gnex have now been on, working [as in got an automated dialler/sms sender running] for over 20 hours and battery is still on 40% :good:
[Samsung Galaxy Nexus] sickopsycho:
Ok heres a question- If I were to install an odexed gapps package and switch runtime to ART... can I still dirty flash my roms when they are updated without experiencing issues? Do I only need to worry about flashing gapps packages? If thats the case does anyone know of a more 0day gapps package thats odexed? I know pagapps has a 0day package but IDK if its odexed or not...

EDIT: NVMD- found the PA-gapps 4.4 ART compatible gapps package (0-day). Havent confirmed working yet but am gonna try a dirty flash over my existing ROM and will report back with results after switch to ART.

EDIT: here it is... http://xdaforums.com/showthread.php?t=2397942

And to make it a little more interesting... can I flash this odexed gapps package over my previously flashed deodexed gapps? As in dirty flash it? Or do I need to clean slate this *****? any experience?

I've been running CM11 (unofficial) build with ART on for a couple of days now. everything works pretty much good, but is it my Gnex faster? I think NOT. now, i don't blame ART for that, maybe it's just a rom issue, but for now i don't see much (if any) improvements over our good ol' trusty 4.3.

[Samsung Galaxy Nexus] nomore66201:
It' s not faster or improved, bit it's quite stable for being an unofficial and incomplete build. My plan was to test it and then return to 4.3, but i think i'm keeping it until official release.

I tested it and at first it seems faster but after a few days you don't notice any difference anymore.
[Samsung Galaxy Nexus] RajatPatel:
Agree. Though there is slight difference in speed while loading app TBH. ART feels just a bit more snappy than Dalvik.

Maybe it's a kernel problem rather than ART. Are you using Mpokang SuperRAM kernel?

I think we shouldn't compare it in terms of performance but in terms of battery life. Because the system doesn't need to compile the app every time you run it.

Anybody using Franco Kernel as well? What is your governor settings? scheduler?

I will try to flash the stock kernel, and compare the performance, then will be back here to report. But so far, it runs oddly slow on my galaxy nexus.
[Samsung Galaxy Nexus] D1BB:
Works great for me. Apps open much quicker, and it might have even helped some with battery. I'm usually running the latest vanir nightly with a dirtyV kernel. Tried liquids 1/25 build but it was too slow. Went back to vanir before I enabled ART, so I can't speak on how it is with that ROM.

I've been using ART for a month and had 0 problems. Not sure if it's placebo or not, but I feel like apps open a little bit faster.
[Samsung Galaxy Nexus] knuspertante:
Hi can anyone give me an answer here? Thanks a lot!
[Samsung Galaxy Nexus] Juice3250:
I am on cm remix and enabled art. It was fine for the first day or two. But then apps started lagging and one of my games, Fast and Furious 6 would force close after a few minutes. I personally couldn't see a huge improvement when I first switched.

I think it's placebo if you ask me. I think we all want ART to work so badly that we convince ourselves that it does.
[Samsung Galaxy Nexus] Nephilim:
What a better thing to say would be that you personally dont think it works in your opinion. Calling ART a placebo could not be further from the truth. So many of you don't notice what you feel is a substantial improvement so first thing you do is call it fake.

You are wrong. Plain and simple.

You have to understand there are many factors.

First, the lower-end the device, the more improvement.

Second, if you are using a rom and kernel with scripts to speed everything up or you have a custom kernel tweaked for higher performance you will notice less difference.

Third, we all know Gnex is a touchy device, ART may just not perform well on your specific device.

Now besides these points, it is fact that because of the way ART compiles the apps upon first boot you will absolutely see improved multitasking, faster opening of apps, better scrolling and improved battery life. These have been proven on video in the form of side-by-side daily usage comparison as well as benchmarks.

Please people, if you don't believe it worked for you personally, just say, "I didn't notice much of a difference", because saying it does nothing or is a placebo just makes it look like you have no idea about anything related to runtime.

[Samsung Galaxy Nexus] dbt816:
Three excellent points! I don't notice much difference in day to day use, but it does reflect in benchmarks FWIW. I will admit that the only downside to ART I've seen is the cache rebuild on first boot... painful for crack flashers :D
[Samsung Galaxy Nexus] Juice3250:
Wow, I will be sure to correctly choose my words next time.

For my ROM and kernel combination, ART didn't help me and made my experience worse on my Galaxy Nexus.

I don't think my opinions were incorrect in the context of where my comment is. It is within the kit kat discussion for the galaxy nexus. ART probably does better on different roms and devices. But, I was simply stating my opinion of it.

Please, if someone has had success running ART with a particular ROM/kernel combination, don't hesitate to throw it out there.
[Samsung Galaxy Nexus] Nephilim:
Wasn't trying to be rude man, I just see too many people calling ART's improvement to devices a placebo or fake when it has been proven the opposite. I do know that some do not notice a substantial difference though so that is fine.
[Samsung Galaxy Nexus] dbt816:
Hehe... use whatever words come out :D From what I've seen, there are ROMs, certain GApps packages, and some apps (seems to be games mostly) that still don't play well with ART. It's an art form to get it humming smoothly (horrid pun intended) :silly:
[Samsung Galaxy Nexus] Juice3250:
Also, from what I've read, evidence for ART is mixed. For some it works and for others they don't see any difference.

I think there are some definite advantages to it but also some bugs that need to be fixed before it comes as the default in future versions of Android. It has definitely come a long way.
[Samsung Galaxy Nexus] AgentSmith:
Don't your 3 arguments disprove the point you are trying to make? The GNex is not a lower end device and all of us are running custom roms with often also a custom kernel. So when people say that ART makes very little difference they're probably right. And in the end it is user experience that counts, not benchmarks or other numbers. Plus I stick to my main reason for using Dalvik: at least it doesn't need to optimize for ages after a ROM update.

Sent from my Kitkatted Galaxy Nexus
[Samsung Galaxy Nexus] dbt816:
Yeah, it will only get better from here... Android 5.0, anyone? :laugh:
[Samsung Galaxy Nexus] Nephilim:
Actually Gnex in today's standards is sub-par so there is alot of improvement there. As for the rom and kernel argument I meant it as people sometimes max their settings because they have multiple batteries and chargers readily available and they are looking for some ridiculous reason for top benchmark scores when really they mean nothing when you aren't using those settings for daily usage. As for the long optimization, its well worth the wait since that one single optimization benefits how quickly apps open and how well the device multitasks.

So, no, nothing I mentioned contradicts my point.
